SMS-based two-factor authentication is vulnerable to SIM swapping — use an authenticator app
SIM swap attacks redirect your phone number to an attacker-controlled SIM, intercepting all SMS codes. Per NIST SP 800-63B, SMS-based 2FA is deprecated for high-value accounts. Use a TOTP authenticator app (Authy, Google Authenticator) or hardware keys (YubiKey). For critical accounts (email, banking, crypto), hardware keys provide the strongest protection available to consumers.

Password length beats complexity — a 20-character passphrase is stronger than P@$$w0rd!
Per NIST SP 800-63B (2020), password complexity requirements (uppercase, symbols, numbers) are counterproductive — they lead to predictable substitution patterns. A random 4-word passphrase like "correct horse battery staple" has 44+ bits of entropy and is easy to remember. A complex 8-character password has ~30 bits. Length wins. Use a password manager to generate and store 20+ character random passwords.
